Replace CassandraUnit test rule with own test rule that honors the external/embedded Cassandra preference. Move Cassandra server initialization into CassandraRule. Introduce a KeyspaceRule to provide managed keyspaces on test class level. Allow cached cluster connections by enabling CassandraRule as class rule. A test that requires a running Cassandra instance needs to either extend the AbstractEmbeddedCassandraIntegrationTest or add the test rule CassandraRule to its test.
Consolidate connection properties (before merging the spring-cql and spring-data-cassandra modules) and simplify config properties classes. Add cleanup after the test run to remove temporary keyspaces. This change allows repeating test runs on a stateful Cassandra instance (e.g. an externally started Cassandra instance). Rename config file and change references to renamed files to support the consolidated connection properties in context config files.
Removed FunkyIdentifierIntegrationTest as it only tests creating tables using reserved Cassandra words. Spring Data Cassandra does not constrain CQL identifiers so maybe later we'll add a test to verify the implemented rules.
Exclude logback-core dependency from cassandra-all. Remove jamm dependency in tests as it's not used. Removed cassandra-unit dependency as the usage is very little. Removed unnecessary hector dependency.
Rename all integration tests to end with "IntegrationTests" and unit tests to end with "UnitTests". Move unit tests to the system under test package to enable testing of package-private types and members. Add missing license headers and author tags. Reformat all test code using the Spring Data Eclipse formatting.
